How to Put an LG Refrigerator in Test Mode

If you have an LG refrigerator, you probably appreciate its various features and long run time. The appliance maker is known for producing high-quality products. However, after a while, everything goes wrong with every appliance. You may easily diagnose a problem with your refrigerator by simply putting it into test mode.

How to Use the LG Refrigerator Diagnostic Mode

Locate the “Freezer Temp” function on your LG refrigerator to put it in Test Mode. Keep in note, however, that some units have a separate “TEST” button. If yours is one of them, instead press the button for the time suggested. Then, simultaneously hit the “Express Freezing” and “Colder” buttons. You can turn on the compressor and freezer fan, the steeping damper if it’s open, the defrosting heater if it’s off, and the display LEDs if they’re all on when in Test Mode 1.

To activate Test Mode 2, repeat the procedures above but hold down the “Express Freezing” and “Colder” keys for three seconds. You’ll be able to test the steeping damper when it’s closed, the defrosting heater when it’s turned off, and the display LEDs when they’re showing number 2 in this mode.

Test Mode 3 follows the same steps as Test Mode 1, with the exception that you must hold the “Express Freezing” and “Colder” buttons for more than three seconds. When the steeping damper is closed, the compressor and fan are turned off, the defrosting heater is turned on, and the display LED shows the number 3, Test Mode 3 allows for diagnostic testing. If the temperature of the defrosting sensor reaches 46 degrees Fahrenheit or higher, the equipment must be reset.

LG Refrigerator Reset

If necessary, you can reset your LG refrigerator once it is in Test Mode 3. In test mode 3, press the “TEST” button or press and hold the “Freeze” and “Cool” buttons for three seconds. This will return your refrigerator to its original settings, which it had before entering test mode.

Once you’ve exited the LG refrigerator diagnostic mode, you’ll be able to tell if the appliance is in good working order or if it requires LG refrigerator repair. If you need a part of your appliance repaired, contact LG using the phone number listed in your owner’s handbook.

Although some refrigerator repairs can be done at home, it is typically more cost-effective, time-efficient, and safer to leave these tasks to a professional. You can contact LG for assistance with repairs, or you can contact a local appliance professional.

Repairing a refrigerator safely

If you decide to handle your own refrigerator repairs, make sure you unplug the appliance before doing anything other than touching the control buttons. When the power is on, never touch any of the unit’s components. To be safe, you can even cut off the electricity at the circuit breaker box.

Before moving a refrigerator, enlist the help of a friend or family member. Refrigerators can be incredibly heavy. Never put a refrigerator on your own, in particular.

How to Reset a Fridge’s Compressor

A refrigerator’s compressor makes use of a low-pressure gaseous refrigerant. When the thermostat of the refrigerator requires more cold air, the compressor turns on and the refrigerant becomes under high pressure, traveling through the cooling coils while fans push chilly air into the fridge and freezer compartments. Resetting the thermostat on the refrigerator allows you to fine-tune the temperature settings, which can result in lower energy expenses. It also allows the refrigerator to defrost and return to room temperature. After restarting, the refrigerator compressor will continue until the required temperature is reached, which will be lower than the ambient temperature.

1st Step: Find the power cord for the refrigerator on the back of the appliance.

2nd Step: Take the power cord out of the outlet. As the power goes out, you may hear knocking noises or a whoosh sound. Turn off the refrigerator for a few minutes.

3rd Step: Inside the fridge, set both the fridge and freezer controls to “Off” or “0.” Reconnect the refrigerator to the power outlet.

4th Step: Set the controls on the refrigerator and freezer to the desired temperature. The “5” setting, for example, would be standard on refrigerators with settings ranging from “0” to “9.”

5th Step: Allow the fridge to acclimatize to a stable temperature for up to one day.
